Do you mean: Is lock out tag out required for minor servicing’ The answer is yes, if the work exposes the worker to hazardous energization, e.g., if a punch press being serviced activates and hits a worker performing the servicing operation. The key is making a proper hazard assessment and implementing proper measures to control the energization and other hazards you identify. Hope this is what you asked. Please feel free to follow up if I missed the target. Glenn
